Applications are invited from graduates with a BSc (First or Upper Second) or MSc (Merit or Distinction), or equivalent, to work within the Wolfson Institute of Population Health (https://www.qmul.ac.uk/wiph/). This 4-year studentship will commence in September 2022 (or January 2023 if preferred) and will be based at the Charterhouse Square Campus. This is an exciting opportunity for a graduate from disciplines related to computational/applied mathematics, informatics or statistics.
Recent technological developments allow collection of a tremendous amount of digital personal multi-omic medical data that includes clinical parameters, serum and urine biomarkers, or genomic data. Some of these analytes are collected over time and organise serial or longitudinal data. Resulting datasets are frequently characterized by small sample size and large number of features. This results in that fact that existing machine learning approaches often fail to analyse such data and are prone to overfitting.
One of the ways to analyse multiple features from patients in such a setting is to use network approach such as parenclitic networks1-3. Although it was shown to be promising in analysing low sample size multidimensional datasets, there are still unsolved methodological issues which preclude successful implementation of this group of methods.
Research aims and objectives
The main aim of this research is to investigate the opportunities that network-based approaches provide for modelling the complex data and how these could be utilized in multi-omic medical setting.
The specific research objectives are:
1) To review existing network approaches available for predictive modelling purposes.
2) To investigate which topological indices are most relevant for parenclitic networks analysis.
3) To investigate how to incorporate longitudinal characteristics into the network setting.
4) To investigate how to make these models transparent and explainable.
This latter is crucial to be able to interpret the results of such black box approach and identify which particular patterns in the data have led to a specific classification result.
This research will address a number of methodological issues which relate to the application of network analysis approaches to predictive modelling. Findings would be particularly important in the context of the analysis of complex multi-omic longitudinal medical data.
